如果您的 iPhone 无法充电，您可能会认为您需要购买一部新 iPhone(get a new iPhone)。
主要指标之一是您的手机未在显示屏上显示充电（闪电）图标，电池图标为黄色(battery icon is yellow)、红色或显示电量不足。更糟糕的是，即使您将手机插入充电，它也不会发出声音，或者什么也没有发生。
本指南解释了您的 iPhone 无法充电的原因以及在注销之前要采取的故障排除步骤。
iPhone不充电的原因(Causes for iPhone Not Charging)
iPhone 无法充电的原因有多种。这些原因包括：
- 电缆故障或充电器问题。
- 电源或墙壁插座可能有故障。这也可能是您计算机的 USB 端口(computer’s USB port)或您正在使用的移动电源耗尽。
- 手机上的一个特定应用程序或几个打开的应用程序可能会消耗大量电量，从而阻止您的 iPhone 充电。
- 您的手机操作系统可能存在问题，导致手机无法正常充电。
- 充电口被堵住了。
- 您的 iPhone 电池可能已损坏或没电。
当您的 iPhone 无法充电时该怎么办(What to Do When Your iPhone Won’t Charge)
根据问题的严重程度，您可以完全更换 iPhone。在您确定手机没用之前，请在 iPhone 不充电时尝试这些故障排除步骤和修复。
1.重启你的 iPhone(1. Restart Your iPhone)
如果您的 iPhone 无法充电，解决问题的最简单、最快捷的方法之一是重新启动它，然后再次将其插入电源。重新启动通常可以解决导致 iPhone 无法充电的任何故障以及您在使用设备时可能遇到的任何其他基本问题。
2. 检查您的电缆和电源适配器(2. Check Your Cable and Power Adapter)
当您购买 iPhone 时，您会在包装盒内找到用于为设备充电的 Lightning 转USB数据线。有时手机可能无法正常充电或完全停止充电，因为您用于连接电源适配器或计算机的电缆可能已损坏或出现故障。
您可以使用iPhone 的第三方充电线进行(third-party charging cable for iPhone)测试，以检查问题是否与 iPhone 的原装充电线有关。但是，如果您确实使用第三方电缆，请确保它标有“Made for iPhone/iPad/iPod”，这表明它来自受信任的公司。
如果您使用的是壁式充电器电源适配器，它也可能导致您的 iPhone 无法正常充电。要解决此问题，请尝试使用另一个电源适配器并检查它是否工作。如果是，请更换电源适配器或尝试使用电脑充电。
或者，如果您的 iPhone 支持无线充电(wireless charging)，请尝试使用无线充电器。
注意(Note)：如果您使用移动电源(using a power bank)为 iPhone充电，但手机无法充电，则可能是移动电源无法正常工作或已死机。在这种情况下，您可以尝试使用不同的移动电源，看看您的设备是否会充电。
3. 检查闪电接头是否有棉绒或粘液 (3. Check the Lightning Connector for Lint or Gunk )
如果您已尝试重新启动或确认数据线和墙壁适配器工作正常，但您的 iPhone 仍无法充电，请尝试检查闪电(Lightning)接头中的粘液或棉绒。
钱包或口袋中的棉绒可能会卡在连接器中，或者端口中有一些碎屑。这些碎屑可能会阻止电源到达手机电池。
检查您的坞站连接器和电缆是否有任何粘糊糊的迹象，如果发现有任何迹象，您可以将其吹出或使用压缩空气进行清理。不要使用棉签或牙签，因为它们可能会损坏小端口内的东西。
如果您自己不方便这样做，您可以访问Genius Bar并让他们为您清洁手机(clean your phone)。
4.检查USB端口(4. Check the USB Port)
要为 iPhone 充电，您需要使用正确类型的USB端口，在本例中为USB 2.0 或 3.0 端口(USB 2.0 or 3.0 port)。如果这就是您要插入的内容，但仍然无法充电，则端口本身可能已损坏。
USB端口中的小型金属连接器也可能略微弯曲，从而无法与手机的充电线正确接触。
将您的 iPhone 插入计算机上的另一个USB端口以测试端口是否损坏，或插入另一个USB设备以查看端口是否工作。这将帮助您排除问题是您的手机还是端口。
5. 在正确的地方为你的 iPhone 充电(5. Charge Your iPhone in the Right Place)
如果您的 iPhone 在尝试了我们迄今为止分享的方法后仍然无法充电，请确保您在正确的位置为它充电。
iPhone 具有高功率需求，这意味着您必须将其连接到直接电源或具有高速USB端口的键盘，以便获得足够的电量进行充电。
iPhone 无法充电的一些地方包括一些键盘和外围设备，例如充电集线器或底座。
6.更换电池(6. Replace Your Battery)
影响 iPhone 电池寿命的最大因素之一是您对 iPhone 的操作，可以是游戏、视频、电子邮件或文字处理等任何内容。
无论您如何使用它，您仍然可以延长手机的电池性能(extend your phone’s battery performance)，因为它的设计具有更高的功率密度以延长电池寿命(battery life)，因此您可以在任何地方做各种事情。
电池重量更轻，使用时间更长，充电速度更快，效率更高。但是，iPhone 的可充电电池的充电周期数是有限制的。
理想情况下，在 500 次完整的充电循环中，iPhone 的电池应保留高达 80% 的原始容量。最终，它可能需要维修或更换，尤其是在您经常为 iPhone 充电的情况下。
Apple为有缺陷的电池提供一年保修，其中包括服务范围，但如果AppleCare超出保修范围，您也可以使用它。访问离您最近的Apple 服务中心(Apple Service)或授权服务提供商，检查电池是否损坏或没电，并完成电池服务(battery service)或更换电池。
让您的手机再次充电(Get Your Phone Charging Again)
如果您已经尝试了所有这些解决方案，但仍然发现您的 iPhone 根本无法充电，请尝试将其置于恢复模式(Recovery Mode)或购买新手机。如果您决定购买一部新手机，并希望从 iPhone 切换到Android，请参阅我们的指南，了解您可以购买的最佳 Android 智能手机( best Android smartphones)以及与之配套的手机保护壳。(protective phone case)

iPhone Not Charging? 6 Fixes to Try
If your iPhone won’t charge, уou may think that you’re going to need to get a new iPhone.
One of the main indicators is that your phone doesn’t show the charging (lightning) icon on display, the battery icon is yellow, red, or shows low charge. Worse still, even if you plug the phone in to charge, it doesn’t make a sound, or nothing happens.
This guide explains why your iPhone is not charging and the troubleshooting steps to take before writing it off.
Causes for iPhone Not Charging
There are several reasons why your iPhone isn’t charging. These reasons include:
- A faulty cable or issue with your charger.
- The power source or wall outlet could be faulty. This can also be your computer’s USB port or the power bank you’re using is drained.
- A specific app or several open apps on your phone could be using a lot of power thus preventing your iPhone from charging.
- There could be a problem with your phone’s operating system that is preventing the phone from charging properly.
- The charging port is blocked.
- Your iPhone battery could be damaged or dead.
What to Do When Your iPhone Won’t Charge
Depending on the extent of the problem, you could replace your iPhone altogether. Before you decide that the phone is useless, try these troubleshooting steps and fixes when your iPhone is not charging.
1. Restart Your iPhone
If your iPhone won’t charge, one of the simplest and quickest ways to resolve the issue is to give it a restart and then plug it into the power source again. A restart usually resolves any glitches that cause your iPhone not to charge plus any other basic issues you may experience with your device.
2. Check Your Cable and Power Adapter
When you buy an iPhone, one of the things you’ll find inside the box is the Lightning to USB cable for charging your device. Sometimes the phone may not charge properly or stop charging altogether because the cable you use to connect to the power adapter or computer may be damaged or faulty.
You can test with a third-party charging cable for iPhone to check whether the issue is with your iPhone’s original cable. However, if you do use a third-party cable, make sure it’s labeled “Made for iPhone/iPad/iPod”, which indicates that it’s from a trusted company.
If you’re using a wall charger power adapter, it could also contribute to your iPhone not charging as it should. To troubleshoot this, try with another power adapter and check whether it works. If it does, then replace your power adapter or try charging using a computer instead.
Alternatively, try using a wireless charger if your iPhone supports wireless charging.
Note: If you’re charging your iPhone using a power bank and the phone won’t charge, it’s likely that the power bank isn’t working properly or it’s also dead. In such a case, you can try using a different power bank and see if your device will charge.
3. Check the Lightning Connector for Lint or Gunk
If you’ve tried a restart or confirmed that the cable and wall adapter are working, but your iPhone still won’t charge, try checking for gunk or lint in the Lightning connector.
It’s possible that lint from your purse or pockets could be jammed into the connector, or there’s some debris in the port. Such debris could block the power from reaching your phone’s battery.
Check your dock connector and cable for any signs of gunk, and if you find any, you can blow it out or use a shot of compressed air to clear it. Don’t use a q-tip or toothpick as these could damage something inside the small port.
If you’re not comfortable doing this on your own, you can visit a Genius Bar and have them clean your phone for you.
4. Check the USB Port
To charge your iPhone, you need to use the right kind of USB port, in this case a USB 2.0 or 3.0 port. If that’s what you’re plugging into and you still can’t get a charge, there’s a possibility that the port itself is broken.
The small metal connector in the USB port could also be slightly bent such that it can’t make proper contact with your phone’s charging cable.
Plug your iPhone into a different USB port on your computer to test if the port is broken, or plug in another USB device to see if the port works. This will help you rule out whether the problem is your phone or the ports.
5. Charge Your iPhone in the Right Place
If your iPhone is still not charging after trying the methods we’ve shared so far, make sure you’re charging it in the right place.
iPhones have high power demands meaning you either have to connect it to direct power supply or to a keyboard with a high-speed USB port so it can get sufficient power to recharge.
Some of the places where your iPhone won’t charge include some keyboards and peripheral devices like a charging hub or dock.
6. Replace Your Battery
One of the biggest factors that affect the iPhone battery’s lifespan is what you do with your iPhone, which can be anything from games, videos, email or word processing.
No matter how you use it, you can still extend your phone’s battery performance because it’s designed with higher power density for more battery life so you can do all kinds of things anywhere.
The battery weighs less, lasts longer, charges faster and more efficiently. However, there’s a limit on the number of charge cycles for your iPhone’s rechargeable battery.
Ideally, at 500 complete charge cycles, your iPhone’s battery should retain up to 80 percent of its original capacity. Eventually, it may need to be serviced or replaced, especially if you keep charging your iPhone frequently.
Apple offers a one-year warranty on defective batteries, which includes service coverage, but you can also use AppleCare if it’s out of warranty. Visit your nearest Apple Service or an authorized service provider to check whether the battery is damaged or dead, and get battery service done or a replacement.
Get Your Phone Charging Again
If you’ve tried all these solutions and still find your iPhone not charging at all, try putting it in Recovery Mode or get a new phone.
